State Pattern

The state pattern, which closely resembles Strategy Pattern, is a behavioral software design pattern, also known as the objects for states pattern. This pattern is used in computer programming to represent the state of an object. This is a clean way for an object to partially change its type at runtime.

Famous quotes containing the words state and/or pattern:

    D--n me, stranger, ef you can’t stay as long as you please, and I’ll give you plenty to eat and drink. Play away, stranger, you kin sleep on the dry spot tonight!
    —Administration in the State of Arka, U.S. public relief program (1935-1943)

    A two-week-old infant cries an average of one and a half hours every day. This increases to approximately three hours per day when the child is about six weeks old. By the time children are twelve weeks old, their daily crying has decreased dramatically and averages less than one hour. This same basic pattern of crying is present among children from a wide range of cultures throughout the world. It appears to be wired into the nervous system of our species.
    Lawrence Kutner (20th century)
